People who keep complaining about JNH's scores was expecting another generic bombastic fantasy score ala the first Harry Potter scores. The Hunger Games is not fantasy, it's a gritty dystopian sci-fi trilogy with influences from roman and greek mythlogy.
Another composer would have treated this franchise with senseless action music, disrepecting the story and the intentions behind it. James managed to get the sounds and styles to the whole franchise in the first score. And he expands these in the same way Powell expanded his sounds on the first Bourne movie. Also giving new use of themes (the love theme was actually used in the first score), and writing a real main theme for the series (the one for Katniss).
Unlike Harry Potter, the themes and sounds for the whole franchise we're founded on the first score, and it's not going to chance.
A composer doesn't write themes or scores to be memorable, but to fit in a film. He shouldn't be forced to write "catchy music and themes" And seems that neither with Francis Lawrence or Shyamalan, who always brought the best from JNH, people can't stop that stupid bias against him, given how they treated the scores he did for them in 2013.
And even worst, because this is the first standalone and sucessful franchise for JNH, but they're ruining it just like they ruined the Harry Potter franchise with their annoying Williams fanboyism. It's a shame.
